In expert mode in video options activate command line and place this command if video delay (begins before) Minus sign : -itsoffset -00:00:00:803or this one if the video delay is plus sign begins (later) : -itsoffset 00:00:00:803

My video the Audio seems to be 6-8ish seconds ahead I see Video_Delay/String : 8s 40ms in my info what would be the proper offset to fix mine?
